The Islamic State group has claimed responsibility for the Thursday night attack that killed a Paris police officer and injured two other officers and a tourist on the Champs-Elysees. Officials haven't said if they believe that claim is credible, but they believe he was operating alone. Here's a look at other extremist attacks in France over the past few years:

July 26, 2016: Two Islamic State militants attack a church during morning Mass in the small town of Saint-Etienne-du-Rouvray in western France, slitting the throat of the 85-year-old priest and wounding an 86-year-old parishioner. One nun escapes and gives the alert, and police shoot both attackers as they leave the church.

July 14, 2016: During Bastille Day celebrations in the Riviera city of Nice, a large truck is driven into a festive crowd, killing 86 people. The driver is shot dead. Islamic State extremists claim responsibility for the attack. The state of emergency in France is extended and extra protection, including robust barriers to prevent similar attacks, is put in place at major sites in France.

June 13, 2016: Two French police officers are murdered in their home in front of their 3-year-old son. The Islamic State group claims responsibility for the attack carried out by a jihadist with a prior terrorist conviction. He is killed by police at the scene.

Nov. 13, 2015: Islamic State militants kill 130 people in France's worst atrocity since World War II. A series of suicide-bomb and shooting attacks is launched on crowded sites in central Paris, as well as the northern suburb of Saint-Denis. Most of those killed are in a crowded theater where hostages are taken.

Islamic State extremists claim responsibility and say it was in retaliation for French participation in airstrikes on the militant group's positions in Syria and Iraq. It leads to the declaration of a state of emergency in France. Police powers are expanded.

Jan. 7, 2015: Two brothers kill 11 people inside the Paris building where the satirical magazine Charlie Hebdo is headquartered in what Islamic State extremists claim is retaliation for the publication of cartoons about the Prophet Muhammad. More people are killed subsequently in attacks on a kosher market in eastern Paris and on police. There are 17 victims in all, including two police officers. The attackers are killed.
